I'm getting some new lowers for my boxxers and was thinking of getting a headlock instead of those pesky star fangled nuts. I'm looking at either getting a Azonic headlock http://www.balleracing.com/Azonic/AzonicHeadLock95Sil.htm or a Answer Aluminium headlock http://www.answerbmx.com/items.asp?deptid=3&itemid=88 instead of using a star fangled nut. Some people love headlocks others hate them. What brand headlocks are good ones? Are headlocks good or not so good to use?
